The association between vitiligo and melanoma is complex. While the incidence of vitiligo in patients with melanoma is higher, the risk for the reverse, ie, the development of melanoma in a patient with vitiligo, is thought to be decreased. This report presents a case of melanoma developing on a non-sun-exposed site in a patient with skin of color and untreated vitiligo.

Although rare, Merkel cell carcinoma (MCC) is a highly aggressive and increasingly prevalent neuroendocrine cancer of the skin. While current interventions, including surgical resection, radiation, and immunotherapy have been employed in treating many patients, those who remain unresponsive to treatment are met with sparse alternatives and a grim prognosis. For this reason, it is of interest to expand the repertoire of available therapies for MCC patients who remain resistant to current primary interventions.

Merkel cell carcinoma (MCC) is an aggressive neuroendocrine skin cancer with high rates of metastasis and mortality. In vitro studies suggest that selinexor (KPT-330), an inhibitor of exportin 1, may be a targeted therapeutic option for MCC. This selective inhibitor prevents the transport of oncogenic mRNA out of the nucleus.

Article Synopsis
  • - Brain cancer is the leading cause of cancer-related deaths in children, and this study aimed to identify risk factors linked to childhood brain tumors in Vietnam, focusing on maternal and perinatal influences.
  • - Conducted at Viet Duc University Hospital, the case-control study involved 220 children aged 0-14, comparing those with brain tumors to age and sex-matched controls with head trauma, using logistic regression to analyze data.
  • - Results indicated that children born to mothers over 30 years old and those with a low pre-pregnancy body mass index were at higher risk for brain tumors, suggesting the need for further research to verify these findings with a larger sample size.

Background: The wide availability of web-based sources, including social media (SM), has supported rapid, widespread dissemination of health information. This dissemination can be an asset during public health emergencies; however, it can also present challenges when the information is inaccurate or ill-informed. Of interest, many SM sources discuss cancer, specifically cutaneous melanoma and keratinocyte cancers (basal cell and squamous cell carcinoma).

Purpose: Previous studies have shown that individuals living in areas with persistent poverty (PP) experience worse cancer outcomes compared to those living in areas with transient or no persistent poverty (nPP). The association between PP and melanoma outcomes remains unexplored. We hypothesized that melanoma patients living in PP counties (defined as counties with ≥ 20% of residents living at or below the federal poverty level for the past two decennial censuses) would exhibit higher rates of incidence-based melanoma mortality (IMM).

  • Foliar diseases caused by specific fungi significantly hinder Welsh onion production in Taiwan, prompting interest in eco-friendly biocontrol methods using endophytes instead of chemical fungicides.
  • The study isolated 109 bacterial and 31 fungal strains from healthy Welsh onion leaves and identified several with strong antagonistic potential against major leaf blight pathogens, particularly highlighting the bacterial strain GFB08 as the most effective.
  • Strain GFB08 demonstrated high disease control through its antimicrobial properties and secretion of cell wall degrading enzymes, suggesting its potential as a biological control agent against Welsh onion leaf blight.

Background: Merkel cell carcinoma (MCC) is a highly aggressive neuroendocrine cutaneous carcinoma aetiologically linked to the Merkel cell polyomavirus (MCPyV). Immune checkpoint inhibitors are currently the first-line therapy for metastatic MCC; however, the treatment is effective in only about half of patients, highlighting the need for alternative therapies. Selinexor (KPT-330) is a selective inhibitor of nuclear exportin 1 (XPO1) and has been shown to inhibit MCC cell growth in vitro, but the pathogenesis has not been established.

Purpose: The social vulnerability index (SVI), developed by the Centers for Disease Control and Prevention, is a novel composite measure encompassing multiple variables that correspond to key social determinants of health. The objective of this review was to investigate innovative applications of the SVI to oncology research and to employ the framework of the cancer care continuum to elucidate further research opportunities.

Methods: A systematic search for relevant articles was performed in five databases from inception to 13 May 2022.

  • The study explores the use of dehydrated complete human placental membrane (dCHPM) allografts as a repair option for Mohs surgical defects on the nose, highlighting that traditional methods may not always be the best choice.
  • Twenty patients who underwent this procedure were assessed for aesthetic and functional outcomes using photography and evaluations by blinded observers.
  • Results showed a favorable scar assessment with a mean score of 8.4 for observers and 12.6 for patients, indicating that dCHPM allografts are a viable alternative, though the study was limited by a small sample size and being conducted at a single institution.

Background: Primary care providers (PCPs) frequently address dermatologic concerns and perform skin examinations during clinical encounters. For PCPs who evaluate concerning skin lesions, dermoscopy (a noninvasive skin visualization technique) has been shown to increase the sensitivity for skin cancer diagnosis compared with unassisted clinical examinations. Because no formal consensus existed on the fundamental knowledge and skills that PCPs should have with respect to dermoscopy for skin cancer detection, the objective of this study was to develop an expert consensus statement on proficiency standards for PCPs learning or using dermoscopy.

Importance: Merkel cell carcinoma (MCC) is a rare and highly aggressive cutaneous neuroendocrine carcinoma with increasing incidence. Cytotoxic chemotherapy and checkpoint inhibitors provide treatment options in the metastatic setting; however, there are no approved or standard of care targeted therapy treatment options.

Objective: To identify actionable alterations annotated by the OncoKB database therapeutic evidence level in association with tumor mutation burden (TMB).

  • The study investigates the effectiveness of surgical stabilization of rib fractures (SSRF) compared to non-operative treatment in patients with thoracic trauma, specifically those with flail chest.
  • A total of 166 patients were analyzed; 31.3% underwent surgical treatment, and while the surgical group had a slightly shorter hospital stay and lower pneumonia rates, these differences were not statistically significant.
  • The findings suggest that while SSRF might lead to some benefits like reduced hospital stay and lower pneumonia incidence, overall mortality rates did not differ significantly between surgical and non-surgical groups.

Article Synopsis
  • Merkel cell polyomavirus (MCPyV) was identified as the main cause of Merkel cell carcinoma (MCC) in 2008, with other human polyomaviruses like trichodysplasia spinulosa virus (TSPyV) and HPyV6/7 linked to skin conditions.
  • Treatment for MCC typically involves surgery and radiation, with new immunotherapy options being explored, though issues like resistance and side effects limit their effectiveness for some patients.
  • The review highlights various treatment methods for related diseases like TSP and PDD, including immunosuppressant reduction and antivirals, while underscoring the need for more research due to the rarity of these conditions.

Purpose: Selinexor is a novel XPO1 inhibitor which inhibits the export of tumor suppressor proteins and oncoprotein mRNAs, leading to cell-cycle arrest and apoptosis in cancer cells. While selinexor is currently FDA approved to treat multiple myeloma, compelling preclinical and early clinical studies reveal selinexor's efficacy in treating hematologic and non-hematologic malignancies, including sarcoma, gastric, bladder, prostate, breast, ovarian, skin, lung, and brain cancers. Current reviews of selinexor primarily highlight its use in hematologic malignancies; however, this review seeks to summarize the recent evidence of selinexor treatment in solid tumors.
